feat(transport): pass ECN CE marks to CC #1689

mxinden · 2024-02-27T13:45:09Z

Pass ECN CE marks received through FRAME_TYPE_ACK_ECN frames to the congestion controler.

mxinden · 2024-03-05T08:59:53Z

Rebasing onto latest #1678 now.

Edit: ✔️

The remaining bits from mozilla#1495 The remaining todo item after this PR is to actually act on incoming CE marks, i.e., trigger a congestion control action. See mozilla#1689
